ARM: dts: exynos: move I2C10 out of soc node on Arndale
I2C10 is represented as i2c-gpio device, thus it is not really a part of soc MMIO bus: exynos5250-arndale.dtb: soc: i2c-10: {'pinctrl-names': ['default'], ... } should not be valid under {'type': 'object'} Link: https://lore.kernel.org/r/20230207210020.677007-7-krzysztof.kozlowski@linaro.org Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
